The Distribution of the Sexes 



diameter. From the height of the column of 

 sand we can estimate the comparative capacity 

 of the two kinds of cells. I will take one at 

 random among my numerous examples of 

 cells thus gauged. 



It comprises thirteen cells and occupies a 

 dihedral angle. The female cells give me 

 the following figures, in millimetres, as the 

 height of the columns of sand: 



40. 44. 43. 48, 48. 46, 47/ 



averaging 45.^ 



The male cells give me: 



32, 35, 28, 30, 30, 31,' 



averaging 31.'' 



Ihe ratio of the capacity of the cells for 

 the two sexes is therefore roughly a ratio of 

 4 to 3. The actual contents of the cell being 

 proportionate to its capacity, the above ratio 

 must also be more or less the ratio of pro- 

 visions and sizes between females and males. 

 These figures will assist us presently to tell
